Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 76
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company manages resources across VPCs in multiple AWS Regions. The company needs to connect to the resources by using its internal domain name. A network engineer needs to apply the aws.example.com DNS suffix to all resources.

What must the network engineer do to meet this requirement?

  • A. Create an Amazon Route 53 private hosted zone for aws.example.com in each Region that has resources. Associate the private hosted zone with that Region's VPC. In the appropriate private hosted zone, create DNS records for the resources in each Region.
  • B. Create one Amazon Route 53 private hosted zone for aws.example.com. Configure the private hosted zone to allow zone transfers with every VPC.
  • C. Create one Amazon Route 53 private hosted zone for example.com. Create a single resource record for aws.example.com in the private hosted zone. Apply a multivalue answer routing policy to the record. Add all VPC resources as separate values in the routing policy.
  • D. Create one Amazon Route 53 private hosted zone for aws.example.com. Associate the private hosted zone with every VPC that has resources. In the private hosted zone, create DNS records for all resources.

Selected Answer: D
Option D is the most appropriate because it involves creating a single private hosted zone for aws.example.com and associating it with every VPC that has resources. This ensures a centralized management approach. With this approach, you can create DNS records for all resources within the private hosted zone, allowing for a consistent DNS suffix across VPCs and regions. Options A, B, and C do not provide a centralized solution or are not suitable for achieving the desired outcome in a multi-VPC, multi-region environment.

Selected Answer: D
Here are the reasons why Option D is the correct answer: It creates a single private hosted zone for aws.example.com. This ensures that all resources in all VPCs can be accessed using the same domain name. It associates the private hosted zone with every VPC that has resources. This ensures that the DNS records for all resources are replicated to all VPCs. It creates DNS records for all resources in the private hosted zone. This ensures that all resources can be resolved by DNS. Option A is not a valid solution because it would create separate private hosted zones for each Region. This would make it difficult to manage DNS records and would not ensure that all resources are resolved under the same domain name. Option B is not a valid solution because it does not apply the aws.example.com DNS suffix to all resources. Option C is not a valid solution because it does not explicitly associate resources in different VPCs across multiple Regions with the aws.example.com domain name.

A is not the best solution if the company manages resources across VPCs in multiple AWS Regions. Consider that company manages resources across VPCs in multiple AWS Regions. Making D more correct.
